#options(*new_options) ⇒ Object

Allows defining convenience option accessors for an array of option names Example: ‘options :color1, :color2` defines `#color1` and `#color2` where they return the instance values `options` and `options` respectively. Can be called multiple times to set more options additively. When passed no arguments, it returns list of all option names captured so far
